Summary: In this study, different shapes of monomers in fractal soot models were established, and their optical properties were evaluated. It was found that the non-sphericity of monomers does not necessarily affect the non-sphericity of the whole soot particle. However, the difference in optical properties caused by different monomer shapes cannot be neglected.

Summary: The structure/composition of nanoclusters plays a crucial role in determining their physicochemical properties. Two different Au-Ag nanoclusters were successfully obtained in this study by controlling the Au/Ag molar ratios, and their structures were confirmed using various techniques. The Au11Ag6 nanocluster exhibited good stability and strong red photoluminescence in solution.

Summary: The structural, electronic, and nonlinear optical properties of colloidal systems formed by gold and silver nanoclusters in different molecular organic solvents were studied theoretically. The results showed that the selected solvents and the nanocluster structure had an impact on the obtained nonlinear optical values, with the dielectric constant being the most significant factor. Additionally, the symmetry of the structures played a critical role in tailoring the desired nonlinear optical response.

Summary: Theoretical study on pulse evolution dynamics in two-stage temporal compression using a graphene-silicon hybrid waveguide as a phase modulator showed that by utilizing saturable absorption (SA) and repressing linearly intensity-dependent absorption (IDA), pedestal-free temporal shape and minimized temporal acceleration can be achieved. Meanwhile, enhancing linearly intensity-dependent refraction (or Kerr effect) contributes to reducing device size and input power of pulse, benefiting the development of graphene-based all-optical modulators in photonic integrated circuits.

Summary: The synthesis and characterization of Bis-glycine hydrochlorobromide monocrystals were conducted using the slow solvent evaporation method. The composition of the crystal was confirmed by XRF, and its crystal structure was determined using XRD and Raman spectroscopy. The crystal exhibits stable orthorhombic structure and its thermal analysis shows its stability up to 444 K. Furthermore, its Second Harmonic Generation efficiency is 0.5 times that of KDP crystal.

Summary: The article studies the structure, optical properties and stability of Anhydrofusarubin. The computational results obtained using density functional theory are in good agreement with experimental data. The study finds the presence of slightly higher energy tautomers and two conformational enantiomer forms. The vibrational and UV-visible absorption spectra were simulated and interpreted.

Summary: In this study, ultrathin Cu (In1-xGax) Se-2 solar cells were investigated using numerical simulations. The impact of different loss mechanisms, such as interface trap density (D-it) and absorber trap density (N-t), on cell performances were explored. Research found that recombination through traps is the primary loss process in the investigated cells. Additional simulations showed significant performance gains for different cell pitch sizes, absorber doping densities, Ga content, and graded bandgap under AM1.5 illumination. The proposed u-CIGS/PERT silicon device offers insights into the optimization of ultrathin-film CIGS solar cells.

Summary: This paper investigates the structural, morphological, and optical properties of nanopowder CdZnS: Cu, as well as the effects of annealing and copper doping on the ternary material CdZnS. Analysis shows that the CdZnS nanopowder has a cubic crystal structure with a preferential orientation of (1 1 1), and the average crystal size and peak intensity increase with annealing temperature. Yellow luminescence is observed under X-ray photons.

Summary: This study investigated the structural and radiation shielding properties of two groups of perovskite ceramics, analyzing their structure using Fourier transform infrared and X-ray diffraction. Different radiation shielding parameters were used to assess their ability to absorb radiation within a specific energy range. The results showed that BaTiO3-ZrO2 had excellent gamma-ray stopping capacity, while SrMnO3-TeO2 was effective in neutron prevention.

Summary: This study fabricated CdS/CdSe heterojunction films at different deposition times using chemical bath deposition. The influence of deposition time on the optical, structural, morphological, electrical, and photoelectrochemical properties of the heterojunctions was investigated. The results showed that the parameters of the films improved with increasing deposition time, and the 10 h deposited CdS/CdSe film exhibited better photocurrent under light illumination.
